Improvement in iron shutters and doors



'UNITED STATES PATE JOHN W. HOYT, OF SPRINGFIELD, MASSACHUSETTS.

IMPROVEMENT IN IRON SHUTITERS AND DOORS.

To all whom it may concern:

Beitknown thatI, JOHNW.HOYT, of Springeld, in the county of Hampden and State of Massachusetts, have invented a new and use- 'ul Improvement in Iron Shutters and Doors; and I do hereby declare that the following is a. full, clear, and 'exact description thereof, reference being had to the accompanying dra-W- ing making a part of this specitication and to the letters ot' reference marked thereon, in which- Figure l is a plan view of a portion of a shutter made according to my invention, being so much as is necessary to show my invention;

and Fig. 2 is a transverse horizontal section of the same.

My invention relates to shutters and doors made of corrugated iron; and consists in the construction of the same, wherein-two or more sheets of corrugated iron are placed together with their corrugations at right angles to each other, and with their edges inclosed Within a channel-iron, said channel-iron forming the edge nish ot' the door or shutter, and is h'rmly riveted to the several sheets of iron as they are thus placed together. Ifit is desirable to have either one or both sides ofthe shutter finished with a Hat surface, a ilat plate of iron may be placed outside the corrugated sheets, and the whole inclosed within the channel-iron, and riveted together and to the channel-iron.

rIhat others skilled in the art may be able to make and use my invention I will proceed to describe the same.

In the drawing, c represents the two outside sheets of corrugated iron. which are placed one on each side of a third sheet, d. The two outside sheets, c, have their corrugations run in a vertical direction, while the corrugations of the third or middle sheet has its corrugations run at right angles to the others or in a horizontal direction. The edge is nished and the whole secured together by the channel-iron a, which completely incloses the edges ofthe sheets on both sides, and is secured to the sheets by the rivets e, which extend through the channel-iron from one side to the other, passing through the sheets c and d, and are headed down at both ends. Doors or shutters made in this manner are very much. stronger than when made with the corrugations of both sheets the same direction.

The appearance of the door or shutter may be changed, as some might prefer, by using two sheets of corrugated iron with the corrugationsV extending at right angles to each other, and

then placing a hat plate of iron outside, upon either one, or both sides, as might be preferable 5 or three sheets of corrugated iron could be used, with a dat plate upon either one or both sides, the door or shutter, of course, being correspondingly strengthened by the additional sheet ot corrugated iron. The door or shutter may also be strengthened by bars ot' dat iron placed across the saine, and when the outside surface is nished tlat, the whole surface of the door or shutter may be divided into panels and ornainented with moldings or beading. The hinges and fastenin gs may, ofcourse, be riveted or bolted upon the channel-iron.

Having thus described my invention, what Iclailn as new, and desire to secure by Letters Patent, is

An improved corrugated iron door or shutter, consisting of two or more sheets of corrugated iron, c d, placed together with their corrugations extending at right angles to each other, and inclosed at their ed ges by the channel-iron a., the whole secured together by the bolts or rivets e, all substantially as described.
